YUANNENGJI The power of LED wall washer determines its projection distance. 一般的に, there are parameters such as 18W, 24W, 36W, and 48W.
しかし, the power is not fixed and can be flexibly adjusted according to demand. High-power LED wall washer generally refers to single-row wall washer, and multi-row wall washer is called linear LED floodlight.
Due to heat dissipation problems, when a single 1W wall washer is projected at a distance of 1 meter, the power should not exceed 36W, otherwise the heat dissipation will be poor and the light decay will be serious. The waterproof test of this type of lamp should be carried out as a test item immediately after the aging test to simulate the real environment to test the real IP protection level of the LED wall washer. This method is usually called thermal testing. After the lamp emits light and heats up, the lamp body will expand and contract. 現時点では, the test can truly test whether the LED wall washer can work normally in harsh outdoor environments and ensure that the lamp has good waterproof and dustproof performance in harsh environments such as wind, rain, and sun.
The voltage of LED wall washer is 220V, 110V, 24V, and 12V, so when choosing a power supply, pay attention to the corresponding voltage. 加えて, there are two voltages, 18V and 36V. Since these two transformers are relatively rare in the market and difficult to match, low-voltage wall washers generally use 24V or 12V.
Since wall washers are usually used outdoors, this parameter is more important and the temperature requirements are relatively high. Usually, we require the outdoor working temperature to be between -40℃ and +60℃. The wall washers use aluminum shells, which have better heat dissipation performance, and ordinary wall washers can meet this requirement.
LED wall washers generally use 1W and 3W LEDs as light sources, but because the technology is not yet mature, 1W LEDs are more common on the market, because 3W LEDs generate more heat, and if the heat dissipation is not good, the light decay will be faster.
2-segment, 6-segment, 4-segment, 8-segment full color, seven colors, red, yellow, 緑, blue, purple, white and other colors. The color temperature is about 2200K, 3000K (warm white), 4000K, 6000K (pure white), 7000K. The luminous angles are generally narrow angle (に関しては 20 度), medium angle (に関しては 50 度), and wide angle. At present, the maximum effective projection distance of high-power LED wall washers is 20-50 meters.
The protection level of LED wall washers must reach IP65, つまり, it must be dustproof and waterproof, with silicone sealing and internal epoxy resin potting, and the waterproof effect is better. This is mainly for the convenience of cleaning and maintenance. LED wall washers are installed outdoors and need to withstand wind, rain, sun and rain.
LED wall washers use PMMA optical lenses and can be customized according to customer requirements. You can choose different luminous colors and luminous effects, such as red, white, yellow, 等, or choose angles such as 15 度, 30 度, 45 度, 65 度, 等. Strong shock resistance, using high-strength die-cast aluminum shell, high-quality high-transmittance tempered glass, high-efficiency reflective cup and end cap. Use silicone ring, corrosion-resistant and impact-resistant.
